WILL/A A. DUKE United States Patent SUCTION EVACUATED URINAL William A. Duke, P.O. Box 53, Snyder, Tex.

Filed Mar. 20, 1959, Set. No. 800,781

2 Claims. (Cl. 4-110) simple, efficient, and practical device of the character indicated above, suitable for both home and hospital use, which eliminates the discomfort and unsanitary conditions accompanying the use of ordinary bed urinals, and the need for assistance in placing, removing the same and disposing of the contents thereof.

Another object of the invention is toprovide a device of the charactei indicatedabove which is composed of a small number of simple and unbulky parts, and which can be readily used, handled, and manipulatedby a bed patient without unusual strain or effort, and whose urine receiving cup and accompanying flexible hose are adapted to be, at the convenience of the patient, taken into the bed, from such as a night table, and removed from the bed and replaced thereon, andrequiresfno emptying of urine therefrom.

A further object of the invention is to provide, in a device of the character indicated above, novel suction drain means, operable by water under pressure from a conventional water supply, and having conduit means connectible to available drain.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

Figure l is a perspective view of a device of the invention, showing the same installed to a pressure water supply pipe, a drain, and disposed relative to a bed and a night table;

Figure 2 is an enlarged fragmentary view of the urinal cup and a portion of a flexible hose associated therewith;

Figure 3 is a fragmentary group view of the urinal cup, shown in longitudinal section taken on the line 3-3 of Figure 2, and the suction drain, portions of which are shown broken away and in vertical transverse section; and

Figure 4 is a vertical transverse section, taken on the line 4-4 of Figure 3.

Referring to detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated device comprises a preferably metallic, longitudinally elongated urinal cup 10, here shown as being of longitudinally elongated oval form, and as having a continuous rounded and concaved upper body contacting edge 12, to conformably fit the body of a female user. It will be understood that for male use, the cup 10 will assume an appropriately different shape. The cup 10 has a flat bottom wall 14 from which rises a circumferential wall 16 which has outer and inner end portions 18 and 20, respectively.

Leading through the wall end portion 20, and securably seated in the accommodating opening 22, as indicated at 23, 1s a rigid straight pipe 24 which lies along the cup bottom wall 14, and terminates in an open intake end 26, which is located close to and is spaced from the wall end portion 18 of the cup. The pipe 24 reaches beyond the inner cup wall end portion 20 and terminates in an open outlet end 28. over which is removably engaged an end of a flexible hose 30. A relatively small diameter air inlet tube 32 extends along the upper side of the pipe 24 and extends through the wall end portion 20, and is secured and sealed in place in the accommodating opening 34, as indicated at 36. The tube has an open end 38 which is located close to the inward side of the wall portion 20, and another open end 40 which is located at substantial dis ance inwardly beyond the wall portion 20, as shown in Figures 2 and 3. The purpose of the air inlet tube 32 is to prevent the development within the cup 10, during operation of the device, excessive suction, which could be uncomfortable or harmful to the user.

The illus rated device further comprises a suction drain assembly, generally designated 42, which comprises a rigid vertical suction pipe 44, which has a laterally curved upper portion 46 and a straight lower portion 48. The upper portion 46 terminates in an open upper end 50 over which the end of the hose remote from the urinal cup 10 is securably engaged.

A vertical tube 54. of a diameter substantially less than that of--tie interior of the suction pipe 44, passes downwardly into the suction pipe through an opening 56, in the convex, side wall 58 of the upper portion 46, in which it is securably sealed, as indicated at 60, and extends downwardly along the related side wall of the lower suction pipe portion 48, as shown in Figure 3. The jet tube 54 has an open lower end 62, which is spaced upwardly from the lower end of the lower portion 48.

The upper end of the jet tube 54 is conne ted in communication with the lower end of a preferably vertical pressure water pipe 64. which, as indicated in Figure 1, is connected by a hand valve fitting 66 to a source of water under pressure 67, such as that available in a hospital or home, preferably on a wall 68 adjacent to a bed 70 to be served by the device. The fitting 66 is equipped with suitable operating means, such as a hand wheel 72, which can be readily reached and operated by a patient in the bed 70. A suitable drain fitting 74, connected to such as the available plumbing (not shown) is connected to the lower end of the suction pipe 44, so that urine and water passing downwardly through the suction pipe 44 are disposed of. When not in use, the device can be coiled and laid upon a night table located within easy reach of the bed 70.

The suction drain assembly 42 further comprises a suitable fitting 76 to connect the lower end of the pressure wa er pipe 64 to the jet tube 54. The fitting 76 may comprise. as shown in Figure 3, a pipe coupling 78 which is threaded at its upper end on the pipe 64, as indicated at 80, and has threaded in its lower end, as indicated at 82, a reducing nipple 84 which terminates at its lower end in a tapered venturi cone 86, in whose lower and smaller end the upper end of the jet tube 54 is securably sealed, as indica ed at 88.

In operation, the bed patient applies the cup 10 to the person and turns on the flow of water under pressure through the suction drain assembly 42 by means of the valve hand wheel 72. The velocity of the water downwardly through the pipe 44 is increased by passage through the venturi cone 86, so that the jet tube 54 produces a high speed jet of water down through the lower portion 48 of the suction pipe 44. As this jet of water expands in the suction pipe below the jet tube, the resultant Water pressure in the lower portion 48 pulls air present in the curved upper portion 46, so that suction is produced in the pipe 24 in the urinal cup which serves to withdraw urine present in the cup 10, downwardly into the pipe 44, from which the urine and water mixture passes to and is disposed of to the drain 74. As above mentioned, the air inlet tube 32 on the cup 10 prevents development of excessive suction in the cup and provides for free suction producing flow of urine therefrom. The patient can, by adjusting the valve hand Wheel 72 dispose of urine in the cup as fast as it is deposited therein.

Because of the relatively small size, weight, and bulk of the urinal cup 10, and the flexibility and maneuverability of the hose, the device can be easily put into and out of a bed and manipulated and operated by a patient of limited strength and ability to move himself.

It is to be understood that the present invention contemplates and embraces any suitable suction operated draining means for the urinal cup 10, and the disposal of the urine thus withdrawn therefrom by any suitable means.

Although there has been shown and described herein a preferred form of the invention, it is to be understood that the invention is not necessarily confined thereto, and that any change or changes in the structure of and in the relative arrangements of components thereof are contemplated as being within the scope of the invention as defined by the claims appended hereto.
